Industry-leading basic performance and track record.
This is a device used to check for leaks, which is the biggest concern when creating a vacuum. It is also called a leak tester. Generally, helium is considered the best tracer for the following reasons: • Light → Easily diffuses • Small molecules → Can penetrate extremely small holes • Chemically stable → Does not contaminate products and is harmless to humans • Almost non-existent in the atmosphere → Prevents false detections by the measuring device • Worldwide service ⇒ Service support is available not only in Japan but globally • Extensive lineup ⇒ Allows selection of the most suitable model for specific applications
